' One of the objects of this invention is to provide a construction which is disposed below the level of the floor of the furnace room so that it is out of the way. Another object is to provide a device which has a plural number of ash receiving receptacles which can be periodically moved beneath the ash pit of the furnace while, at the same time, making possible the ready removal of any desiredash can.i A still further object of the invention is to provide a rotary ash receiving device which is freely supported and rotated upon its bearings regardless of any weight that may be placeduon the covers to the device. Other objects will. become apparent from the following description of the embodiment of the invention shown in the drawings. i

The floor surface of the furnace room is indicated at 1 below which there is built a pit 2 which may be lined as indicated at 3 with metal or the like or which may be left in the natural surface finish of the concrete or other material of which the pit is formed. The pit is preferably circular and in the center ofthe floor 4 thereof there is rigidly secured, asby the bolts 5, a foot plate 6 centrally recessed on itsupper face to serve as a socket for a vertical post 7 preferably formed as shown in Fig. 1. That is to say said post comprises a heavy round main section with reduced end portions the lowermost 8 of which seats in the recess of the foot plate 6 and the upper 9 of which is adapted to support the covers of the pit.

A circular plate 10 is fitted around the lower post spindle 8 with a roller or other suit able thrust bearings 11 interposed between said plate and the shoulder of said spindle. The plate 10 has a central upwardly extending collar, internally threaded, to receive the lower end of a cylindrical casing 13 encompassing the major portion of the post"? in spaced relation thereto so that grease or other lubricant maybe placed within the intervening space to make the rotary movement of the device easier. A similar roller thrust bearing 15 is disposed on the upper spindle 9 between the shoulder of the post and a cap plate 16 which likewise has a central collar 17 internally threaded to engage the upper end of the casing 13. I

'The base of turntable of the device comprises the lower plate 10 to which is rigidly secured the inner ends ofradially extending angle iron members 18 the outer ends. of which are rigidly interconnected by angle iron members 19 and gusset; plates 20, see Fig, 2. Also there are providedaintermediat-e angle iron members 21 the ends of which are rigidly secured by gussets 22 to intermediate points of the radial angles 18. The angle members are all so assembled that. there is formed a perfectly plane seat of triangular shape to receive the bottom of an ash can 25. In order that the turntable with its ash cans may be more stable there-are providedstay rods 26 connecting the outer extremities of the angles 18 with the upper plate 16 all-in a manner as will be readily understood from the drawings.

There thus results a skeleton construction of star shape providing a plurality of tritip angularly shaped spaces each for the reception of an ash can, the drawings having six such spaces. In thus making the device hexagonal in form the angles 18 and 19 can be precut all of the same length and drilled at the same points to receive the rivets or bolts by which they'are secured inplace. The stay rods 26 extend obliquely upwardlyand inwardly to thetop plate 16 wherethe upper ends of said rods pass through openings in said plate into inclined recesses27 in order; that the threaded ends may receive nuts by which the rods are tightened. ,It is to be observed from Fig. 1 that said recesses are so cast in the plate 16" thatthe upper ends of. said rods together with their nuts will lie completely below the upper surface of said plate. In between each pair of recesses 27- thereis provided a triangularly shaped hole 28 preferably passing entirely: through the plate, each of these holes for a purpose that will presently appear. i In order that each can 25 may be positively retained in its correct positionon the turntable, and with particular reference to Figs.

' 2, 3 and 4, it will be observed that the upwardly extending flanges of the angle members 18 constitute stops for the lower'end portion of each can, and that there is provided an adjustable bracket member 30 to.

engage each can on the side farthest away from the post 7. Within each outer angle iron member 19, and substantially centrally disposed thereof, there is provided a filler block 31 to engage the face of the inwardly extending end '32 of a bracket 30, said end 32 being centrally'slotted as at 33. to receive a bolt 34 by which thebracket is secured to the angle 19. It thus is made possible to accommodate ash cans of different sizeswithin certain limits, merely by positioning the bracket 30 so that each can is held onthe turntable at three points of circumferential contact.

The upper spindle 9 of the post 7 extends above the top plate 16 and engages a central socket of a hexagonally formed cap plate 40 which has cast-on its upperface an upstanding'ridge 41, see Figs. 5,8 and 9.- parallelly disposed to the perimeter of the plate 40 to provide a seat and an abutment for the inner ends of each cover sectionof the pit.' In other words, there are providedinlthisparticular construction six coversections' comprising plates each generally indicated by the numeral 12 and of triangular shape except that the outer edge is circular as indicated at 43 to:fit: the perimeterof the. pit 2, and the opposite apex is cut off-toprovide a straightedge portion-44 to-rest in the aforee mentioned seatand against the abutment comprising theouter side ofthe hexagonalridge 41. .The other sides of each cover section are made to conform with radii of the circular it and are further provided withofi-sets as indicated in Fig. 6 at 18 so that the edge of one .rcover section may supportthe edge of the adj acent section. and the uppersurfaces of all of said sections will lie in the same plane. To render this possible the aforementloned seats for the cover sections are formed with a recess 4E9 of; a size to accommodate theofi'sets l8 oi the sides ofthe cover sections, all as will be readily understood from the drawings. v Two of the cover sections, preferably diametrically opposed, are apertured as. indi- .cated at 15, one of said-sections being so dis posed that its aperture is in registry with the ash pit of afurnace, indicatedinthe drawingsj by the dotted line 46, sothat the ashes from the grate may be directed toand fall through saidaperture into one; of, the cans 25. "The aperture of the other cover section has a lid 17 which, when removed,permits the sweepings of the furnace room floor to be directed into oneof-thefash cans, said lid 47 being; sunk or recessedwithin thev cover section to provide aqflush floor surface, .see Figs. 1 and 5. similar lid may be provided for the aperture inthe. furnace ash pit if found necessary because of faulty draft.

A. hexagonal lid 50 fitswithin the hexagonal ridge 4:1, and from Fig; 1 it will bereadily seen that when the turntable is not toberotatedthe entire exposed surface ofthe cover. sections is in the plane of the furnace room floor, and further it will be seen that any weight placedon the cover .sectionswill be borne thereby without affecting any of-the rotatable parts. In otherwords the post 7 is adapted by this invention to always remain stationary, the ash cans and their turntable being adapted for rotation about said pOSt. I

The means for rotating the turntable com prises a bar 51 having an upstanding handle 5 at .Qne a a d a der na e p on 53 t n so the opposite end,- the extreme end of the portion 53 being triangularly shaped in cross section to provide a key at which will fit each of the triangular openings 28 in the top plate 16 of the turntable. There is also pro vided a circular collar immediately ad jacent said hey the periphery of said collar extending slightly beyond the apices of the key and serving as a stop as will be readily understood.

The hexagonal plate 10 supporting the cover sections is provided with an arcuate slot 56 the ends of which are enlarged as indicated at 57 to a. diameter sufiicient to permit the collar 55 of the operating handle to pass therethrough, but the width of the slot 56 is less than the diameter of said collar so that it is possible to pass the collar 55 through the slot only at an enlarged end thereof. The slot 56 is located in the plate 40 immediately over'and in line with the path oftravel of the triangular openings 28 of the top plate 16 of the turntableyand further located to control the positions of the cans 25. In other words, when a can 25 iscorrectly positioned below the ash hole 45, in the cover section under the furnace, a triangular hole 28 will be in registry with each enlarged end 57 of said slot. When said can has been filled with ashes the lid 50 is removed to uncover the slot 56 and the key end of the operating handle passed through one of the enlarged ends of said slot to engage the opening 28 therebelow. Upon movement of the handle from this position to a position occupying the other limit of said slot, see Fig. 8 the top plate 16 will have been rotated a distance equal to bring the next adjacent can 25 into correct position under the ash opening 45. By making the slot 56 as above described it is impossible .to

insert or remove the handle 51 without hav- 1 ing a can in correct position.

Vhen a can, filled with ashes, is to be removed from the turntable, one of the cover sections, preferably 60 and containing the lid 47, is lifted, no bolts being provided to secure this section to the adjacent sections. The opening thus made in the furnace room floor is ample to permit the removal of a can, and if the can positioned therebeneath is not the one desired, the turntable may be rotated until such can appear: The handle 51 should be left in operative position during the transfer of cans to and from the turntable to insure the proper setting of the turntable, when the cover section 60 is replaced, thus leaving a can under the ash pit opening 45. From Fig. 1 it will be seen that the cover sections are disposed in close-proximity to the tops of the cans which permits observations to be made through both apertures 45 in the cover sections to ascertain the quantity of ashes in all the cans. Further it will be seen that the entire weight of the turntable andcans is suspended from thetop plate 16 which in turn is carried by the non-rotating vertical post .7 and, through the thrust bearing 15, permitted free rota- ;may vary the details of construction as well i as arrangements of parts without departing from the spirit ofithe invention, and it is therefore not desired to be limited to the foregoing disclosure except as may be demanded by the claims.
